Quick Care Tips For Postharvest Grapes
November 13, 2013 Researchers at University of California-Davis recommend keeping these pointers in mind to keep your vineyard healthy after harvest:
For table grapes:
- Monitor for vine mealybug on fruit and foliage.
- Steam-sanitize equipment before moving to uninfested areas if vine mealybug is present.
- Look for European fruit lecanium scales on leaves in the San Joaquin Valley. Treat if needed just before leaf drop.
- Continue to mark and remove vines or cordons infested with diseases such as: Eutypa dieback, Pierce’s disease, and bot canker.
- Continue to monitor for western grapeleaf skeletonizer on early harvested varieties.
- Sample for nematodes in the Coachella Valley if not already done in spring.
- Check sticky traps for glassy-winged sharpshooters.
- Check for grape thrips and red-headed and green sharpshooters
For wine and raisin grapes:
- Monitor for vine mealybug, and if present treat immediately after harvest. To reduce risk of transferring vine mealybug, do not place winery pomace in the vineyard; compost pomace or cover piles securely with clear plastic.
- Look for symptoms of Pierce’s disease on vines and flag for removal.
- Look for European fruit lecanium scales on leaves.
- If you desire a cover crop, seed after harvest.
